Description

  The present invention relates to a natural extract containing polyphenol, a natural extract containing polyphenol oxidase, and a deodorant composition effective for deodorizing menstrual odor including cyclodextrin and a sanitary napkin containing the same. .

  In general, in the case of feminine hygiene products, i.e. sanitary napkins, most of the surface sheets come into contact with the skin, and the texture and absorbability of the sheets and prevention of blood leakage affect the performance of these products. However, another important performance in sanitary napkins products is to suppress the menstrual odor generated by physiological blood absorbed during use of sanitary napkins. The odor generating compound may be present in the components of fluid excretion such as sweat, physiological fluid and physiological blood, or may be generated while the components of such fluid excretion are decomposed. As a result, odor-related compounds exist in a wide range and include fatty acids, ammonia, amines, sulfur-containing compounds, ketones, aldehydes and many of these derivatives.

  One of the mental pains of people who use sanitary napkins is that the smell of physiological blood absorbed by sanitary napkins leaks to the outside and people around them may notice or discomfort People who have anxiety and a strong sense of anxiety may avoid going out during their menstrual periods and may even develop interpersonal aversion. In particular, in the summer, the bad smell becomes more severe due to the decay of physiological blood, and the problem is further increased.

  In order to remove such odors caused by physiological blood, various types of odor control agents are used. However, physiological blood contains various chemical substances that generate odors. For a wide range of odors, there is a problem that this cannot be effectively suppressed. In the case of activated carbon used as a foul odor suppressant, hydrogen sulfides have a deodorizing effect, but amines do not have an effect, and there is a problem of giving aesthetic discomfort to consumers in terms of hue. There is. In addition, mugwort and herb extracts may be used as deodorants, but these depend on pharmacological effects and fragrances, and their effects are weak to fundamentally remove the decay and odor of physiological blood. In order to remove odors, natural medicines derived from natural products are used, but this depends only on the traditional literature that is effective in removing odors, and there is sufficient scientific evidence. Absent. Therefore, development of a direct deodorant composition excellent in the deodorizing effect on the physiological blood composition is required.

  As a result of earnest research to provide a composition having an excellent deodorizing effect on menstrual odors, the present inventors have found that natural extracts containing polyphenols known to have a deodorizing action, and oxidation of polyphenols. When a natural extract containing an enzyme that promotes hydration and cyclodextrin are mixed, it is found that the menstrual odor component has an excellent deodorizing effect, and the deodorizing effect of the sanitary napkin containing this is confirmed. Thus, the present invention was completed.

  Accordingly, an object of the present invention is to provide a deodorant composition having an excellent deodorizing range and deodorizing efficiency.

  The present invention relates to a deodorant composition comprising a natural extract containing polyphenol, a natural extract containing polyphenol oxidase, and cyclodextrin, and a sanitary napkin containing the same.

  The deodorant composition of the present invention contains polyphenol, an enzyme that oxidizes this, and cyclodextrin, amines such as trimethylamine and ammonia, which are main components of menstrual odor, and sulfur compounds such as methyl mercaptan, etc. It is effective in removing a wide range of bad odor sources and has a continuous and powerful menstrual odor removal effect. In addition, since the composition of this invention is comprised only from the edible natural extract, there exists an advantage that it is harmless to a human body.

It is a GC / MS analysis result graph which showed the component (control group graph) which appeared by the analysis result of the menstrual odor component, and the component (Example graph) which remain | survived after deodorizing by an Example.

  The present invention includes a natural extract containing polyphenol, a natural extract containing polyphenol oxidase, and a cyclodextrin, and a deodorant composition effective for deodorizing menstrual odor and a sanitary napkin containing the same About.

  Hereinafter, the present invention will be described in detail.

  In the present invention, polyphenol is an extract extracted from an edible natural plant, and the natural extract containing this is harmless to the human body and is strong against malodorous components such as ammonia, amines and aldehydes. Deodorizing effect is shown. In the present invention, the natural extract containing the polyphenol is one or a mixture of two or more selected from the group consisting of Thyme, Melissa, coffee, green tea, and green tea. can do.

  All the extracts in the present invention can be easily extracted through a known extraction method widely used in the art, and the extraction method is not limited.

  The present invention uses polyphenol oxidase together with the polyphenol. Conventionally, only a compound containing polyphenol was often used for deodorizing effect, but when a natural extract containing polyphenol was oxidized with polyphenol oxidase, highly reactive quinone was produced, Focusing on the point that the quinone produced at this time reacts with a malodorous substance and exhibits an excellent deodorizing effect, a high deodorizing effect can be achieved by using polyphenol and polyphenol oxidase together. In other words, by mixing a polyphenol-containing natural extract with a polyphenol oxidase that promotes oxidation, autooxidation is promoted, and malodor can be removed with a high deodorization rate within a short time. As the natural extract containing the polyphenol oxidase, one or a mixture of two or more selected from the group consisting of natural extracts of garlic, seri, potato and banana can be used.

  The present invention is characterized in that cyclodextrin is used together as a deodorant composition.

  As the cyclodextrin, one or a mixture of two or more selected from the group consisting of α-type, β-type, and γ-type cyclodextrin is used. Cyclodextrins are characterized by having a ring structure, and such a ring structure is effective for masking bitterness, miscellaneous taste, specific odor, malodor, etc., and can be used as a malodor deodorant or fragrance.

  In the present invention, cyclodextrin is used together with the polyphenol and polyphenol oxidase, and by using cyclodextrin together, a malodorous substance component that does not react with polyphenol and quinone produced by polyphenol oxidase is obtained. As a result, the deodorization rate can be greatly improved as compared with the case where the cyclodextrin is collected together with the ring structure, which is a structural characteristic of cyclodextrin, and cyclodextrin is not used together. Therefore, when using the composition of the present invention, there is a feature that a wider deodorization range can be shown and a higher deodorization rate can be shown than when an existing deodorant composition is used.

  Moreover, since all the compositions of the present invention are composed only of edible natural extracts, there is an advantage that they are harmless to the human body.

  The deodorant composition for removing menstrual odor of the present invention has a solid content of 10 to 50% by weight of the natural extract containing the polyphenol, and a solid content of 10 to 10% by weight of the natural extract containing the polyphenol oxidase. It is preferable to mix 50% by weight and the solid content of cyclodextrin as 40 to 80% by weight. In the case of the natural extract containing the polyphenol or polyphenol oxidase, there is a problem that the deodorization rate is inferior when the solid content is less than 10% by weight. There is a problem that the off-flavor of odor increases. In the case of cyclodextrin, when the solid content is less than 40% by weight, there is a problem that the deodorizing effect by cyclodextrin is inferior, and when it exceeds 80% by weight, the deodorizing effect by polyphenol and polyphenol oxidase is present. There is a problem that falls.

  In the case of producing a sanitary napkin including the composition of the present invention as described above, there is an advantage that a sanitary napkin having a very excellent effect of suppressing menstrual odor can be produced.

  EXAMPLES Hereinafter, although an Example demonstrates this invention concretely, this invention is not limited to these.

Production Example 1: Production of Extract Containing Polyphenol To 100 g of Melissa containing polyphenol, 200 ml of 0.1 M potassium phosphate buffer solution (pH 7.0, 4 ° C.) was added and homogenized with a mixer (Waring blender) for 5 minutes. Thereafter, a supernatant obtained by centrifuging (10,000 × g) for 30 minutes at 4 ° C. was obtained, and after adding 20% by weight of dextrin and freeze-drying, Melissa powder obtained by pulverization was used.

Production Example 2: Production of Extract Containing Polyphenol Oxidase 200 ml of 0.1M potassium phosphate buffer solution (pH 7.0, 4 ° C.) was added to 100 g of syringa containing polyphenol oxidase and mixed with a blender (Waring blender). After homogenization for 30 minutes, the mixture was filtered using a woolen cloth. The filtrate was centrifuged at 10,000 ° C. for 30 minutes at 4 ° C., and 20% by weight of dextrin was added and lyophilized. Thereafter, sengiku powder obtained by pulverization was used.

Example: Manufacture of a deodorant composition having a menstrual odor inhibitory effect In order to produce a deodorant composition having a menstrual odor inhibitory effect, polyphenol oxidation using Melissa as a substrate containing polyphenol As the enzyme, sengoku extract was used, and as the cyclodextrin, an α content of 30 wt%, a β content of 10 wt%, a γ content of 10 wt%, and a dextrin of 50 wt% were used.

  The final menstrual odor control deodorant is manufactured by mixing 25 wt% of Melissa powder obtained through Production Example 1, 25 wt% of sengiku powder obtained through Production Example 2, and 50 wt% of cyclodextrin. did.

Comparative Examples 1-3: Production of deodorant composition having effect of suppressing menstrual odor For comparison with the deodorant composition of the examples of the present invention, activated carbon (Comparative Example 1), Melissa powder (Comparative Example 2) A composition of Melissa powder and Sengiku powder (Comparative Example 3) were produced through the following methods, respectively.
Comparative Example 1: 0.1 g of activated carbon was used.
Comparative Example 2: 0.1 g of Melissa powder was produced in the same manner as in Production Example 1.
Comparative Example 3: 0.05 g Melissa powder produced through Production Example 1 and 0.05 g sengiku powder produced through Production Example 2 were mixed and used.

Experimental Example 1: Inhibitory effect of menstrual blood odor main component (trimethylamine) In order to measure the inhibitory effect on trimethylamine, the main component of menstrual odor, of a deodorant composition containing polyphenol, polyphenol oxidase and cyclodextrin, The degree of odor suppression was measured using a gas detector tube (Gastec).

  10 μl of 30% trimethylamine solution (15% in water) was added to 0.1 g of the composition of the above example as an odor-inducing source solution. As a control group, 2 ml of a 0.1 M potassium phosphate buffer solution (pH 7.0) and 10 μl of a 30% trimethylamine solution (15% in water) as an odor-inducing source solution were placed in a 50 ml dark brown bottle. As comparative examples, 0.1 g of each of the compositions of Comparative Examples 1 to 3 was used, and 10 μl of 30% trimethylamine solution (15% in water) was used as the odor-inducing source solution.

  Each test bottle was shaken in a 37.5 ° C. water bath for 10 minutes and then gas detector tube No. 180 was used to measure the concentration of malodorous sources remaining in the upper head space of the container. The measured values of each gas detector tube obtained by repeating the above experiment three times are shown in Table 1 below.

  As can be seen from Table 1 above, in the examples according to the present invention, the deodorization rate of trimethylamine is 90%, which is significantly higher than that of the activated carbon, Melissa or Melissa and Sengiku used as comparative examples. It is a high result. Specifically, when only Melissa was used, there was no deodorizing effect, and when Melissa and Sengiku were used together, the deodorization rate was only 50%, and the cyclodextrin of the present invention was used together. It was confirmed that the effect was significantly lower than the case (deodorization rate 90%).

Experimental Example 2: Inhibitory effect of menstrual odor main component (ammonia) In order to measure the depressant composition containing polyphenol, polyphenol oxidase and cyclodextrin, the inhibitory effect on ammonia, which is the main component of menstrual odor, Gas detector tube (Gastec) No. The odor suppression degree was measured using 3La.

  A 25% ammonia solution (15% in water) was used as the odor source solution. Except that 25 μl of the odor induction source solution was used, the odor component suppression effect was measured in the same manner as in Experimental Example 1, and the results are shown in Table 2 below.

  As can be seen from Table 2 above, in the case of the examples according to the present invention, the deodorization rate of ammonia was 100%, which was significantly higher than that in the case of mixing activated carbon, Melissa or Melissa and Sengiku used as comparative examples. It is a high result. Specifically, when only Melissa is used, the deodorizing effect is only 10%, and when Melissa and Sengiku are used together, the deodorizing rate is about 80%, and the cyclodextrin of the present invention is used together. It was confirmed that the effect was inferior to that when used in (deodorant rate 100%).

Experimental example 3: Inhibitory effect of menstrual odor main component (methyl mercaptan) In order to measure the inhibitory effect of deodorant composition containing polyphenol, polyphenol oxidase and cyclodextrin on methyl mercaptan, the main component of menstrual odor In addition, a gas detection tube (Gastec) No. 71 was used to measure the degree of odor suppression.

  Methyl mercaptan sodium salt solution (15% in water) was used as the odor source solution. Except that 3 μl of the odor induction source solution was used, the odor component suppression effect was measured in the same manner as in Experimental Example 1, and the results are shown in Table 3 below.

  As can be seen from Table 3 above, in the case of the examples according to the present invention, the deodorization rate of methyl mercaptan is 100%, which is almost the same as the case of mixing activated carbon used as a comparative example, Melissa and Sengiku. The result was equal. However, when only Melissa is used, it turns out that there is almost no deodorizing effect.

  From the results of Tables 1 to 3, the composition of the present invention has a deodorizing effect on the main components of menstrual odor such as trimethylamine, ammonia and methyl mercaptan, which are main components of menstrual odor, It can be seen that the rate is also very high compared to other compositions. Therefore, when the composition of the present invention is used for a sanitary napkin or the like, it is expected that it can be utilized as a deodorant composition that is extremely superior in terms of its deodorizing range and deodorizing effect over the existing composition.

Experimental Example 4: Inhibitory effect on menstrual odor composition In order to measure the inhibitory effect on the menstrual odor composition of a deodorant composition containing polyphenol, polyphenol oxidase and cyclodextrin, a menstrual odor similar composition Was prepared with reference to a Japanese patent (Kao Corporation, JP 2007-198829), measured by GC / MS, and the components of the prepared menstrual odor-like composition are shown in Table 4 below.
